Abstract: BEHIND WELL CASING WATER FLOW DETECTION SYSTEM                  (D#74,199-1-F) ABSTRACT OF THE DISCLOSURE         Equipment for the detection of undesired behind casing water flow in a producing well is provided.  A well logging sonde having a modular fluid tight structure is disclosed. Basically, three modules which when joined together form a fluid tight assemblage comprise the sonde.          A first module houses a 14 MEV neutron generator and a 125 kilovolt high voltage power supply for operating the neutron generator.  A second module houses dual spaced gamma ray detectors for detecting characteristic gamma rays from the decay of radioactive nitrogen 16 at two different longitudi-nal distances from the neutron source.  A third module houses control electronics and data transmission circuits for controlling the neutron generation and receiving detected signals from dual gamma ray detectors and for transmitting data to the surface from the sonde.  The modules are con-structed so that they may be assembled with the neutron generator either above or below the dual detectors while maintaining the same spacing distances from the generator to the detectors.  Surface instrumentation for receiving and interpreting the gamma ray measurements are also provided.     I

Abstract: IMAGING SYSTEM                 ABSTRACT OF THE DISCLOSURE           A photosensitive member having at least two electrically operative layers is disclosed.  The first layer comprises trigonal selenium which is capable of photogenerating holes and injecting the photo-generated holes into a contiguous charge trans-port layer.  The charge transport layer comprises a transparent electrically inactive organic resinous material containing from about 15 to about 75 percent by weight (throughout) of bis(4-diethylamino-2-methylphenyl)phenylmethane.  The charge transport layer while substantially non-absorbing in the spectral region of intended use, is "active" in that it allows injection of photo-generated holes from the trigonal selenium carrier generating layer, and allows these photo-generated holes to be transported through the charge transport layer.  This structure may be imaged in the conventional xerographic mode which usually includes charging, exposure to light and development.

Granted: 1981-04-21
Abstract: ABSTRACT OF THE DISCLOSURE            This invention relates to fired iron-ore pellets and a process for producing the same.  The process includes the steps of:  crushing iron ore to be pelletized; adding carbonace-ous materials of grain sizes of 0.1 to 3 mm in diameter to the thus crushed iron ore in an amount of up to 4% by weight for mixing therewith; pelletizing a mixture thus prepared; and firing the pellets thus obtained; thereby providing pellets, in each of which there are intentionally dispersed macro-pores of sizes of 0.1 to 0.3 mm in diameter, at a ratio of up to 25% to the entire pores contained therein.  Pellets produced by this process demonstrate superior  properties in both high temperatures and in non-temperatures and have a high gas efficiency as well as being free of retardation of reduction even in an elevated tempera-ture range in a blast furnace.  These pellets are also free of the softening and sticking phenomena found in the prior art thereby improving the productivity of the blast furnace and reducing the coke ratio.

Abstract: Abstract of the Disclosure.  A self-contained, battery powered well logging instrument is pumped down the interior of a drill pipe string having a catcher sub at its lower end.  When the logging instrument latches into the catcher sub, the pumped fluid circulation is blocked, after which increased pump pressure switches a valve assembly to recreate circulation and energize the logging instrument to the standby position.  An accelerometer in the logging instrument detects the upward movement of the instrument and switches the circuitry from standby to the record mode.  The output from a clock controlled by the downhole accel-erometer is recorded along with the logging information and is synchronized with pipe footage measurements and with a similar such accelerometer and clock at the earth's surface which are responsive to the movement of the pipe string at the earth's surface.  The recorded logging samples are thus related to true depth by correlating with the data simultaneously recorded at the earth's surface.  As an alternative embodiment, the logging instrument is attached to the drill pipe prior to running the pipe into the borehole.

Abstract: STRIPLINE QUADRATURE COUPLER                      ABSTRACT    The coupler accepts four independent RF input signals, divides each-input into four equal parts, and applies each part to one of four adjoining output ports.  Each input signal divided part is phase shifted a multiple of 90° whereby the output ports, taken in the proper order, are in phase quadrature.    The novel coupler comprises four hybrid couplers, all of which are fabricated on a dielectric substrate.  The hybrid couplers are located on the substrate in a unique interleaved configuration whereby intercouplings are formed between selected hybrid couplers.  The interleaved construction results in the electrical length of all intercouplings being controlled and, preferably, all are the same length.

Abstract: "Abstract of Disclosure"      The dissolving and/or dispersing of relatively large proportions of reclaimed rubber into molten paving asphalts is facilitated by incorporating into the asphalt a minor porportion of a highly aromatic, high-boiling, high-flash-point mineral oil. The resulting mixtures can be held at temperatures above 300°F for substantial periods of time without becoming too viscous for convenient handling, thereby facilitating the application thereof to roadways.  The rubberized asphalt mixtures are particularly useful in the form of stress absorbing membrane interlayers between old, damaged pavement surfaces and an overlayer of new asphalt concrete, for providing chip-seal coatings over old pave-ment, as crack fillers in Portland Cement concrete or asphalt concrete pavements, and bridge deck waterproofing membranes.
